PENGUKURAN DISTRIBUSI DINAMIS KONSENTRASI GAS KARBON MONOKSIDA (CO) MENGGUNKANA WIRELESS SENSOR NETWORK

Abstract

Increasing population growth rate followed by pollution can cause carbon monoxide (CO). Carbon monoxide gas, including air pollution, then with the necessary monitoring devices for controlling the gas concentration CO gas in the environment. Tool made in the form of 5 points randomly distributed sensors to measure the concentration of CO gas. Measurements carried out safely which can be monitored in real time remotely using telemetry (remote measurement) with jarigan Wi-Fi. The minimum system microcontroller ATmega8535 to convert analog to digital data from the sensor. To respond to the physical symptoms of the changes in the concentration of CO gas used MQ-7 sensor utilizing as komuniksai UART serial and Wi-Fi as a data transmission. ADC value readings from the sensor MQ-7 converted into concentration values in the form ppm. Data that is sent over Wi-Fi will be acquired into a computer and stored in the database. Concentration of data processing in the form of a graph where the results of measurements carried out showed that the concentration changes which occur at any time change depending on the wind direction. If the value of the concentration is high, the colour is black, whereas if a low concentration is purple.
